5.6.14 Phase Protection Settings

F098 = Phase Rotation Trip
Factory Setting = 0 (Disabled)
Range = 0 (Disabled), 1 (A-B-C), or 2 (B-A-C)
The TE2 Series is set up to monitor an expected Phase
Rotation and trip if it changes. Control of this is divided into two
categories: Enable or Disabled and Expected Sequence. The
default setting is disabled.
Setting this function to disabled (setting 0) is useful in
applications where the TE2 Series is going to be used
downstream from an existing reversing contactor or to avoid
conflicts with other protection devices.
On large motors where large multiple conductors are used, it
may be easier to change the Expected Sequence in the TE2
Series starter rather than swap the conductors.
F099 = Phase Rotation Trip Delay
Factory Setting = 1 second
Range = 1 - 20 seconds
Provides a time delay to prevent nuisance trips from short-
duration transients. Using default settings, if the phase rotation
is detected to be different for more than 1 second the starter will
trip.
F100 = Phase Loss Trip Delay during Stop
Factory Setting = 1 second
Range = 0 - 20 seconds (0 = Disabled)
Provides a time delay to prevent nuisance trips from short-
duration transients while stopped.
Note: Based on loss of input voltage on one phase while
decelerating or stopped.
F101 = Phase Loss Trip Delay during Running
Factory Setting = 1 second
Range = 0 - 20 seconds (0 = Disabled)
Provides a time delay to prevent nuisance trips from short-
duration transients while running.
Note: Based on current in one phase dropping below 20% of
FLA (F001), while starting or running.
